香榧(Torreya grandis)是我国特有的珍果树种,诸暨“枫桥香榧”盛名中外。产地群众历来采用大砧嫁接方法保持良种性状。由于这种方法培苗周期较长(4～5年)工本高,技术复杂,影响香榧良种建设和生产发展的速度。为了解决香榧快速繁殖技术,我们针对香榧野生资源丰富,根系肉质幼嫩再生力强等特点,自1980年起对香榧进行了根段作砧嫁接育苗试验。经四年来的不断摸索,嫁接成活率一般在70～80％之间,1～3年生根
Torreya grandis (Torreya grandis) is a peculiar rare species of fruit in China, Zhuji “Hongqiao Fengqiao” prestigious home and abroad. Origin of the masses have always used a large stake grafting methods to maintain seed traits. Because of this method, the plantlets have a long period (4-5 years) with high cost and complex technology, which affects the speed of the construction and production of sweet clover. In order to solve the rapid propagation technology of Ostrinia pubescens, we aimed at the rich resources of wild Osmanthus fragrans and the strong regeneration of root succulent. After four years of continuous exploration, the survival rate of grafting is generally between 70 to 80%, 1 to 3 years root
